It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-5450 in the wild and no public exploit code.\n\nAffected product: com.nextcloud.client. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2019-5450/ (Markdown: https://insights.sbomify.com/CVE-2019-5450/index.md)","id":"CVE-2019-5450","markdown":"https://insights.sbomify.com/CVE-2019-5450/index.md","name":"CVE-2019-5450","record":{"aliases":["GHSA-x6fc-pmf5-67rv"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nextcloud Android app","requires_auth":"none","summary":"Attackers can inject HTML into directory names to alter the app's header bar styling, potentially misleading users.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"nextcloud","vendor":"nextcloud"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page"}],"description":"Improper sanitization of HTML in directory names in the Nextcloud Android app prior to version 3.7.0 allowed to style the directory name in the header bar when using basic HTML.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Cross-site scripting in com.nextcloud.client","id":"CVE-2019-5450","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2019"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in com.nextcloud.client","id":"CVE-2019-5451"},"packages":[],"prev":{"headline":"Information disclosure in Nextcloud Server","id":"CVE-2019-5449"},"products":["com.nextcloud.client"],"published":"2019-07-30","related":[{"cvss_score":9.8,"headline":"SQL injection in com.nextcloud.client","id":"CVE-2019-5454","kev_date_added":null,"published":"2019-07-30"},{"cvss_score":7.5,"headline":"SQL Injection in FileContentProvider (GHSL-2021-1007)","id":"CVE-2021-43863","kev_date_added":null,"published":"2022-01-25"},{"cvss_score":6.8,"headline":"Auth bypass in com.nextcloud.client","id":"CVE-2019-5455","kev_date_added":null,"published":"2019-07-30"},{"cvss_score":6.5,"headline":"Information disclosure in Nextcloud Android App (com.nextcloud.client)","id":"CVE-2021-22905","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":6.5,"headline":"Information disclosure in Nextcloud iOS app (it.twsweb.Nextcloud)","id":"CVE-2021-22912","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":6.1,"headline":"Auth bypass in Nextcloud Android","id":"CVE-2019-15615","kev_date_added":null,"published":"2020-02-04"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can inject HTML into directory names to alter the app's header bar styling, potentially misleading users.","url":"https://insights.sbomify.com/CVE-2019-5450/"}
